A fluid $(0\mathrm{.}5k\frac{g}{s})$ enters a pipe of length $1$ m at $60C.$ The pipe wall temperature is a constant $20C.$ Assume the flow is fully developed. The pipe has a diameter of $3$ cms $.$

Fluid properties: $876k\frac{g}{m^3},0\mathrm{.}144\frac{W}{m}K$ and kinematic viscosity $=2\mathrm{.}4{10}^{-4}\frac{m^2}{s}$ Prandtl number $=120.$

Calculate the exit temperature of the fluid $($in $C),$ the wall heat flux $($in W$)$ and the pressure drop $($in Pas$).$

REDO the problem with a mass flow rate of $5k\frac{g}{sec}.$
